# DESCRIPTION

These functions implement string manipulation operations over wide-character strings. For a detailed description, refer to the documents for the respective single-byte counterpart, such as memchr(3). The wcswcs() function is not a part of ISO/IEC 9899:1990 (“ISO C90”) and ISO/IEC 9899/AMD1:1995 (“ISO C90, Amendment 1”), the wcsstr() function is strongly recommended to be used.

# STANDARDS

These functions conform to ISO/IEC 9899:1999 (“ISO C99”) and were first introduced in ISO/IEC 9899/AMD1:1995 (“ISO C90, Amendment 1”), with the exception of wcslcat() and wcslcpy(), which are extensions. The wcswcs() function conforms to X/Open Portability Guide Issue 4, Version 2 (“XPG4.2”).
